Pit Bull Trailer Restraint System - Kawasaki ZX6R, ZX10R, Z1000 It offers the following three advantages: 2) The motorcycle rests on the trailer floor with no added force on the suspension. This means no more blown fork seals caused by heavy strap tension, and a flat tire on the bike will not change how securely the bike is held. 3) This is the quickest, easiest system available for loading/unloading your bike for transport. One person can easily roll the bike into place until it is captured by the restraint. 4) Never a need for a front chock again
